My idea for a super power/biopunk AU
As the title says, this is an AU where, instead of the original mech suits, the main cast gains super powers from bio manipulation.
The main crux is that this version of Tabane is not an engineer but a biologist, and has created a symbiotic artificial creature that allows a temporary metamorphosis with super powers. The most basic powers are bio shifting (necessary for metamorphosis) and weak telekinesis (which is needed for flight and defense)
Still deciding on the powers of the other girls, but Chifuyu is the easiest. Her power is enhanced bio shifting, allowing her to create weapons from her own mass. This is perfect for her fighting ability, while still being obviously a prototype (literally just a maxed out basic power)
Of course, our main boy Ichika has to have powers, and I thought the best power in this version would be a mimic power. Basically a power that lets him copy his friends powers, but he needs to manually master them through training. This amps up what makes the original so special, and by extension what makes the series so unique. It also gives us more screen time of Ichika interacting with the girls.
That's my idea at least, let me know your thoughts
